Transcription and RNA polymerase Transcription by RNA polymerase. An RNA strand is synthesized in the 5′ → 3′ direction from a locally single stranded region of DNA. (After E. J. Gardner, M. J. Simmons, and D. P. Snustad, Principles of Genetics, (more...).n most prokaryotes, a single RNA polymerase species transcribes all types of RNA. Figure 10-7 shows the structure of RNA polymerase from E. coli. We can see that the enzyme consists of four different subunit types.

- Basically, RNA polymerase's role is very similar to that of DNA polymerase. RNA polymerase is an enzyme that is used during transcription in the nucleus. Similar to DNA polyme … rase, RNA polymerase codes for the complementary nucleotides to a DNA strand. Instead of thymine though, uracil codes with adenine.
